10-(2-Fluorophenyl)-9-(4-methoxyphenyl)-3,3,6,6-tetramethyl-3,4,6,7-tetrahydroacridine-1,8(2H,5H,9H,10H)-dione

In the title compound, C30H32FNO3, the central heterocyclic ring of the tetrahydroacridinedione system is planar while the two outer rings adopt envelope conformations. The buckling angle between the two halves of the acridinedione system is 10.61 ( 2)degrees, which shows the relative planarity of the system. The dihedral angle between the planes of the aromatic rings is 6.13 ( 2)degrees. The crystal structure is stabilized by three intermolecular C-H center dot center dot center dot O hydrogen bonds that generate C( 10) chains together with R-2(2)(16) and R-3(2)(15) ring motifs. A weak C-H center dot center dot center dot pi interaction further stabilizes the crystal structure.
